Question

Match the column I with the column II and mark the appropriate choice.

	Column I		Column II
(A)	Estimation of hardness of water	(i)	cis - Platin
(B)	Detection an estimate of nickel	(ii)	EDTA
(C)	Electroplating	(iii)	Dimethylglyoxime
(D)	Treatment of cancer	(iv)	Potassium dicyanoargentate

• A. $\left(A\right)\to \left(i\right),-\left(B\right)\to \left(iv\right),-\left(C\right)\to \left(ii\right),-\left(D\right)\to \left(iii\right)$
• B. $\left(A\right)\to \left(ii\right),-\left(B\right)\to \left(iii\right),-\left(C\right)\to \left(iv\right),-\left(D\right)\to \left(i\right)$
• C. $\left(A\right)\to \left(iii\right),-\left(B\right)\to \left(i\right),-\left(C\right)\to \left(iv\right),-\left(D\right)\to \left(ii\right)$
• D. $\left(A\right)\to \left(iv\right),-\left(B\right)\to \left(i\right),-\left(C\right)\to \left(iii\right),-\left(D\right)\to \left(i\right)$

Answer 1

The correct option is B $\left(A\right)\to \left(ii\right),-\left(B\right)\to \left(iii\right),-\left(C\right)\to \left(iv\right),-\left(D\right)\to \left(i\right)$

i. EDTA is used for estimation of hardness of water.

ii. Dimethyl glyoxime is used for detection and estimation of Nickel.

iii. Silver complex are used for electro plating.

iv. Cis-platin is used for treatment of cancer.
